I found this aluminum capsule at REI this weekend. It does not seem particularly sturdy but I bought one to use as a Vaseline/Cotton Ball tinder container (US$3).<br><br>This alongside a BSA HotSpark on a key ring would make a good, small set. I have not filled mine yet, but I think I can probably get 4-5 cotton balls inside.<br><br>http://www.rei.com/cgi-bin/ncommerce3/Pr...grfnbr=10642126
